IMPROVEMENT IN TOOLS FOR SHAVING LEATHER Specification. forming part ofLetters Patent N 0. 180,667, dated August 1, 1876; application filed May26, 1876.

To all whom it may concern Be it known that I, JAsON SMITH, of Boston,in the county of Sufl'olk and State of Massachusetts, have inventedcertain Improvements in Tools for Shaving Leather, ofwhich the folwiththe leather to be operated upon, to which is hinged an arm, carrying aknife having two cutting-edges, and which may beset at any desiredangle. A gage bears against the edge of the leather, and, beingadjustable to the knife, the operator is enabled to make the bevel ofany width that may be desired. A spring, attached to and projectingbeyond the gage, has a bearing on the upper surface of I the leather ateither side of the knife, and

serves to prevent the leather from curling before the knife.

In the drawing, Figure 1 is a perspective,

view of my invention. Fig. 2 isa plan of the under side, a being theknife, 12 the gage, and c the spring. Fig. 3 is a longitudinal section,

showing the different parts as when in operation, A being the handle, Bthe hinged arm I held in place by the brace l), secured by screw d. f isthe thumb-screw that secures the knife (1 to the arm B. The gage b issecured to the handle by the screw 9. Fig. 4 is an enlarged view of theknife on and spring 0 in operation, as representing a piece of leather,the tool moving in the direction shown by the arrows.

The operation of using my'invention is as follows: The leather is laidon the cuttinghoard, and held in place with the left hand. With the toolin the right hand it is placed so that the gage will bear against theedge of the leather and the spring on its upper surface. When the toolis moved in either direction, the knife will shave the leather to thebevel and thickness at which the knife is set.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination, the handle-A, hinged arm B, two-edged knife a, andthumb-screw f, all substantially as and for the purpose set forth.

2. in combination, the handle A, hinged knife a, gage b, and spring 0,all arranged and operating substantially as described.
